I don't understand your posting.
The
"why" is very clearly stated in the article linked in the OP. The title very clearly states
"New policy due to limited supply issues at stores". The article goes on to say:
"Lundberg said, "We are trying to take care of as many customers as possible because supply is limited at this time." He said Walmart stores are monitoring supply issues daily and will address purchase limits once supply issues are resolved."
So the answer to your question is very clearly stated.
You may choose to believe that or not. However, at this time there is no supporting evidence whatsoever that there are any other ulterior motives, including anything related to Obama's gun control meetings. Anything about that would be pure conjecture. If you, or anybody else, actually come across such evidence, by all means post it.
Time will tell us whether or not there are ulterior motives.
An interesting human behavioral question here, though:
I am quite sure that there would be any number of naysayers who would, upon future confirmation of their suppositions, readily come forth and cry "I told you so!". How many naysayers, do you suppose, would so readily come forth with future evidence they were wrong and say "Thank goodness I was wrong!"?
I suspect, in the coming weeks and months, that when the current craze dies down and supplies come back up approaching normal levels, we'll see Walmart's current policy of limits change back.
Let's do our part to remain calm and observant in the meantime.
